Hello! I'm translating a text that explains how to engrave a serial number on metal, and there are various techniques, one of which is CASTING. So how might I translate this term in Spanish (marking the number by casting it into the metal)? Here's the English sentence: By engraving, casting, stamping (impressing), or otherwise conspicuously placing or causing to be engraved, cast, stamped (impressed), or placed on the frame or receiver thereof an individual serial number. And my Spanish attempt: Al grabar, FUNDIR??, imprimir, o colocar de manera evidente o provocar que quede grabado, FUNDIDO??, impreso o colocado en el marco o la caja el número de serie. Thanks in advance!
